Got some clustering stuff cleaned up.  Error messages and detection improved.  Also found some buggy code.  Will need to clean it up further...  Now about to carefully schedule backprop phase with only certain links learning -- down to a quite low mse before even starting the first flocking loop in which only a very different set of links will learn.  I may want to include link from hidden neuron's output to its very own input. -- perhaps want to do this during the flock phase while I'm also training the cross-recurrent links.
